Jika P = 1, 2, 3, 4 , diberikan relasi atas P sebagai berikut :

P1 = (1, 1), (1, 2), (2, 1), (2, 2), (3, 4), (4, 1), (4, 4)

P2 = (1, 1), (1, 2), (1, 4), (2, 1), (2, 2), (3, 3), (4, 1), (4, 4)

P3 = (2, 1), (3, 1), (3, 2), (4, 1), (4, 2), (4, 3)

P4 = (1, 1), (1, 2), (1, 3), (1, 4), (2, 2), (2, 3), (2, 4), (3, 3), (3, 4), (4. 4)

P5 = (1, 1), (1, 2), (2, 1), (2, 2), (2, 3), (3, 2), (2, 4), (4, 2), (3,3), (4,4)

P6 = (2, 1), (2, 2), (2, 3), (3, 2), (2, 4), (4, 2), (3, 4), (4,4)

P7 = (1, 1), (1, 2), (3, 3), (3, 4), (4, 3)

Manakah dr ke-tujuh kekerabatan diatas yg masing-masing bersifat : refleksif, simetrik, antisimetrik, transitif & yg bukan simetrik sekaligus bukan antisemetrik.

#TolongBantuDijawabMastah2BRAINLY

Refleksif = P2, P4, P5

Transitif = P1, P2, P4, P5, P6

Simetrik = P1, P2, P5, P6
